Problems solved by technology

[0003] However, all these are small-step improvements. If the scheduling optimization is constrained by the physical power plan arranged years ago and months ago, there will inevitably be loss of efficiency and waste of resources.

Embodiment Construction

[0069] In order to facilitate the understanding of the content of this solution, further explanations are given below in conjunction with specific embodiments.

[0070] Because inter-provincial tie lines are also resources on the power generation side and can be regarded as power plants to participate in power distribution, the type of power plants in this embodiment includes inter-provincial tie lines.

[0071] Take the typical dry day in a province in 2016 as an example, the 24-hour load forecast curve for the typical dry day is as follows: figure 2 Shown. The minimum start-up load of the typical daily safety and stability constraints of Kuda University is 6299MW. The transmission power of the inter-provincial tie-line in the day is priority power generation. The predicted power generation curve is as follows image 3 Shown. From this, the schedulable load curve can be calculated as Figure 4 Shown. On this basis, the base load, waist load and peak load corresponding to the sch...

Abstract

The invention provides a power generation optimization scheduling method based on load area electricity prices. The method comprises steps of dividing a schedulable load curve into a base load, a waist load and a peak load so as to divide different areas into a large number of energy blocks and mark the energy blocks at different positions with different electricity prices; then filling the energyblocks with the power generated by different power plants with different electricity prices; and finally obtaining the optimal power generation optimization scheduling result. The method enables eachpower plant to fill the energy blocks corresponding to the load curve with the electricity price and power of load characteristics in combination with its own power generation characteristics, thereby mobilizing different types of power plants to use their peak load regulation advantages to earn more profits, to consciously participate in system peak load regulation, and to greatly relieve the system peak load regulation pressure.

Description

Technical field [0001] The invention relates to the field of electric power technology, and in particular to a method for optimized dispatching of power generation based on load zone electricity prices. Background technique [0002] Power grids often face huge peak-shaving pressure during operation. In recent years, the peak-valley time-of-use price method has been used to adjust from the load point of view, but there is a lack of attention to power market transactions. The current electricity market trading mode mostly adopts medium and long-term electricity trading rules. The latest medium and long-term trading rules propose that the planned electricity is broken down to the month, centralized bidding, contract transfer, deviation assessment, emergency trading, pumped storage and pumped electricity special trading, auxiliary services, etc. Standardization and innovation, if implemented and coordinated by mechanisms such as the deregulation of power generation plans, can further...
